There are very few people who can defeat the doctor in this situation but 98% of the people that have been mentioned would not even have so much as a chance. Doctor Doom really?, I've argued this on comic vine, he stands no chance against the Doctor.

@SamJaz: My favourite doctors would probably be William Hartnell,Matt smith and David tennant.Im edging towards matt as my one and only favourite because He generally Is The DoctorAs for making a master character, That is the best idea i've heard all day...

@Kuma_From_Argentina said:@hudyman: You're going to make a Doctor based character? I have trouble seeing him fit in a anime/manga world like the one we try to show in the Viceverse. But you never know, you can make an awesome Manga Doctor XDYup, that was the idea :P
